Trouble shooting 3

INDOOR UNIT Error Method:

Wired Remote Controller

Communication Error

Detective Actuators:

Indoor unit Controller PCB

Wired Remote Controller

Forecast of Cause:

1. Connection failure

Check Point 1 : Check the connection of terminal

After turning off the power.

Check & correct the followings.

Check the connection of terminal berween Wired Remote Controller and indoor unit,

and check if there is a disconnection of the cable.

Check Point 1-2 : Check Wired Remote Controller and Controller PCB

For AS* G __ KGTB

Check Voltage at CN300 (Terminal 1-2) of UTY-TWRXZ2 (Communication kit).

(Power supply to Remote control)

>> If it is DC12V, Remote control is failure. (Controller PCB is normal)

>> If it is DC 0V, Controller PCB is failure. (Check Remote control once again) >> Replace Controller PCB

For AS* G __ KMTB

Check Voltage at CNC01 (Terminal 1-3) of UTY-TWBXF2 (Communication kit).

(Power supply to Remote control)

>> If it is DC13V, Remote control is failure. (Controller PCB is normal)

>> If it is DC 0V, Controller PCB is failure. (Check Remote control once again) >> Replace Controller PCB

For AR type

Check Voltage at CN300 of Controller PCB. (Terminal 1-3, Terminal 1-2)

(Power supply for the Remote Control)

>> If it is DC13V, Remote control is failure. (Controller PCB is normal)

>> If it is DC 0V, Controller PCB is failure. (Check Remote control once again) >> Replace Controller PCB

For AU type

Check Voltage at CN14 of Controller PCB. (Terminal 1-3, Terminal 1-2)

(Power supply for the Remote Control)

>> If it is DC12V, Remote control is failure. (Controller PCB is normal)

>> If it is DC 0V, Controller PCB is failure. (Check Remote control once again) >> Replace Controller PCB

Upon correcting the removed connector or mis-wiring, reset the power.

Check Point 2 : Wire installation Wrong RCgroup setting

Wrong wire connection in RCgroup (Please refer to the installation manual)

The number of connecting indoor unit and Remote controller in one RCgroup were less than 16 units.

Check Point 2-1 : Check Indoor unit controller PCB

Check if controller PCB damage.

Change controller PCB and check the Error after setting remote controller address.

Indicate or Display:

Error code : 12

Detective details:

Upon receiving the signal more than 1 time from Wired Remote or other Indoor

unit, but the same signal has not been received more than 1 minute

(3 Wire type), 2.5 minute (2 Wire type)

2. Wired Remote Controller failure

02-04

Outdoor unit : No indication

3. Controller PCB failure

>> Replace Remote control
